Our brain cells do look a lot like a map of the universe – but that doesn't mean they're the same thing.
Nervous about how southern television viewers would react, NBC executives closely monitored the filming of the kiss between Nichelle Nichols and William Shatner.
U.S. Air Force
The career arc of Nichelle Nichols – the first black woman to have a continuing co-starring role on TV – shows how diverse casting can have as much of an impact off the screen as it does on it.
“We’re all mad here.”
"Sometimes I've believed as many as six impossible things before breakfast." To understand the universe, we need more Mad Hatter mathematicians.
Cloud Gate, 2004. Stainless steel, 1,006 x 2,012 x 1,280 cm.
Anish Kapoor made “Cloud Gate”, a giant bean-shaped mirror in Chicago. Visitors play with the light in the city and its surroundings, where our future lays.
The other galaxies are there, but they are hiding a very long way away.
We are in the Milky Way. If you travelled on an extremely fast spaceship for more than two million years, you would reach our neighbour, the Andromeda galaxy. All other galaxies are even further away.
The moon is our closest neighbour and our best hope for building capacity to explore space.
Space mining has the potential to provide a greater supply of resources either for being exploited locally for construction or being sent back to earth.

A new name on a few military badges doesn't imply an escalating arms race.
The US wants a ‘Space Force’ to be the sixth branch of the US military.
Those who speak of the inevitability of war in space will fuel a race to the bottom, and see even more energy towards an arms race in space.
The blood moon myths are many and varied, but, at the end of the day, it's just an eclipse.
Jeff Bezos plans to charge US$200,000-300,000 for a trip to outer space. And it's going to cost him an astronomical amount of money.
Nobody knows for sure where black holes lead to.
The pull created by a black hole is so strong that if you get too close to one – even if you are travelling away from it at the fastest speed it is possible to go – you will never be able escape.
The existence of wormholes is not forbidden by our current theories of the universe. So we can say that they do exist in theory.

A wormhole is like a tunnel connecting two places in space. They would be incredibly useful and are great for science-fiction stories.
The problem is we haven't found any evidence of them existing.
What could a ‘relativistic camera’ capture on the way to Alpha Centauri?
An astronomer suggests an idea to piggyback on the ambitious Breakthrough Starshot project that aims to send nano spacecraft to Alpha Centauri at a major fraction of the speed of light.
From moon landing to space arms race.
Trunp's new policy could lead to the militarisation of outer space and the beginning of a new space arms race.
In fact, some things are slowing the Earth down or could change its spinning in the future.
To answer this tricky question, we have to look back in time to when the Earth was born, 4.5 billion years ago.
Should schools be charged large sums to teach students about space science?
Will new communications licensing costs make small satellites so expensive that they can't be used for student education?
About a century ago, we didn’t even know that galaxies existed.
Mai Lam/The Conversation NY-BD-CC
Pretty much as soon as we understood what galaxies were, we realised they are all moving away from each other. And the ones that are further away are moving faster. In short, the universe is expanding.
The things you can do with an amaterur telescope.
With a little bit of knowledge and a few pieces of equipment you too can look at the night sky and see it as a cosmologist does.
